Abstract

1526274 Apparatus for the reproduction of colour copies AGFA-GEVAERT AG 11 Sept 1975 [11 Sept 1974] 37452/75 Heading H4F Apparatus for the line-by-line recording on a record carrier of colour separation records by means of light beams S 1 -S 3 , wherein the colour separation records are formed in succession at spaced apart exposure stations, comprises means for producing an adjusting signal dependent on the position of the first colour separation record for effecting fine adjustment in the superimposition of the subsequent colour separation records on the first such record. The means for producing an adjusting signal may consist of photoelectric devices D 2 , D 3 which are arranged to scan an adjusting mark on the record carrier. The adjusting mark may be produced on the carrier at the first exposure station by a marking device M.
